Application filed September 8, 1916. Serial No. 119,009.

To all whom it may concern:

Be it known that 1, WILLIAM 0. Grass rm, a citizen of the United States, and a resldent of Phoenix, in the county of Maricopa and State of Arizona, have invented a certain new and useful Improvement in Display Devices, of which the following is a specification.

My invention is an improvement in display devices, and has for its object to provide a device of the character specified by means of which a series of cards bearing advertising or other matter, may be displayed in succession, the displayed cards being returned to the magazine for redisplay in turn.

In the drawings:

Figure 1 is a plan view with the cover broken away;

Fig. 2' is a side view with parts in section;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4: is a section on the line 1-4 of Fig.

3, looking in the direction of the arrows adjacent to the line; and

Fig. 5 is a section on the line 5-5 of Fi 2.

n the present embodiment of the invention, a suitable base 1 is provided upon which is mounted a motor 2 of suitable con struction, and the display apparatus to be described,-a cover 3 being provided for covering the said apparatus and the motor. The display apparatus comprises a magazine for receiving the cards indicated at 4 which carry the display matter, and the magazine is composed of a front plate 5 which is se-- cured to the base, and holding strips 6 at the rear, the said strips engaging the edges of the cards to hold them in place. The rear of the magazine is open. Above the cards are arranged three rollers 8, and 9 respectively, said rollers being secured to shafts 10,11, and 12, the said shafts being in the same horizontal plane. The peripheries of the said rollers move in contact, and the cards are fed up between the rollers 7 and 8, and down between the rollers 8 and 9.

A pick-up mechanism is provided for picking up the rearmost card and delivering it to the rollers 7 and 8. The said mechanism comprises a shaft 13 upon which is mounted a curved arm 14 of resilient material having at the free end thereof a friction block 15. The shafts 10, l1, l2, and 13 are journaled in a supporting frame 16 and of transparent material, as for instance glass. A ide partition 19 is arranged in the extension behind the glass, in position to hold the display card just behind the glass. The lower end of the guide partition is bent at an angle as indicated at 20, so that it is parallel with the position of the cards as they leave the magazine. The lower end of this angular portion is rounded to prevent engagement thereof by any of the cards and the angular portion of the partition guides the cards into the constricted space between the body of the partition and the sheet of glass. As soon as the card passes into the constricted portion and the lower edge thereof is free from the rollers 7 and 8, the resiliency of the card will cause the lower portion thereof to swing forwardly into the full line position of Fig. 3, and when the cards so swing they rest upon the angular upper ends 21 of holding arms 22 which are secured to a shaft 23 journaled in the frame 16. This shaft 23 has a radial arm 24 outside the frame, and a coil spring 25 is arranged between the said arm and the frame for normally holding the arms in the full line position of Fig. 3.

The shaft 23 is provided with a second radial arm 26 extending rearwardly and upwardly and this arm is adapted to be engaged by a cam arm 27 on the shaft 13 before mentioned. When this cam arm enr 18. *As 'soon as the upper end of'the card is free'from between the rollers 7 and 8 the gages. the arm 26 it will oscillate the shaft in a direction to move the lugs 21 of the holding arms 22 from beneath the card and the rollers 8 and 9 are so arranged that when the'card is released it will drop down beneath the rollers 8 and 9 and will be delivered by these rollers back into the maga- I connected by a belt 30 with a pulley 31 on themotor shaft. The shaft 28 is also pro- 'vided' witha pinion 32which meshes with a gear wheel 33' on the shaft 8. At the opfposite end from the gear wheel 33' the shafts 10, 11, and 12 have intermeshing pimons 34, 85 and 36. The shafts l0 and 12 are mounted in slidable bearingblocks 37 which are slidable in a guide 38- in' the frame toward and from the shaft'll, and springs 89 are provided for normally pressing the bearing blocks and the said shafts 10 and 12 toward the shaft 11.

Withthis arrangement, the three rollers 7, 8, and 9 are pressed together while they may yield when a card is beneath them. The'shaft 11 is provided with a worm wheel 40' whichmeshes with a worm ll on the upperend' of a shaft42 held in a bearing to rear, and the. motor being started, once bracket 43 on the frame This shaft 42 has i worm 4:4: at its lower end which meshes s5 fore mentioned The extens1on'17 is supwith aworm wheel d5 on the shaft 13 beported by the frame and the cover is slotted to permit the passage of the extension.

The

"card; will immediately drop between the roll- 7 l ersS and '9 and will be returned to the magazine at the front of those remaining in the magazine, so that all within the magazine will be displayed before the said card is again displayed. Any desired display matter may be arranged upon the display. cards and the said matter may be complete on each card or it may be supplemental to that on the preceding or following cards.

I claim 1. A display device comprising a magazine having an opening in its back, a shaft journaled behind the magazine and having a pick-up arm provided with a friction block for engaging the rearmost card to lift the same, an inclined'display frame above the magazine with which the magazine-communicates, the said frame having means for guiding the card from the magazine into position behind the inclined front thereof,

three parallel friction rollers above the magbetween the foremost rollers, said magazine having means for delivering the. card from the foremost roller into the magazine, spring controlled'means for holding the card in the display frame and controlled by the rotation of the shaft carrying the pick-up arm, and means for rotating said shaft and the rollers.

2. A display. device comprising a magazine, a shaft journaled upon the magazine and having a pick-up arm for engaging the rearmost' card in the magazine to lift the same, an inclined display frame above the magazine with which the magazine communicates, the said frame having means for guiding the card from the magazine into the frame, means above the magazine for engaging the lifted card and moving it into the display frame, normally operative means for holding. the card in the display frame, means controlled by the pick-up arm for releasing the holding means as a new card is lifted, and. means for moving the display card into the magazine when the said'card has been released.

3. A display device comprising a magazine for display cards, a. display frame above the magazine, means between the zine. for display cards, a display frame above. the same, means for lifting the rearmost card'in the magazine at predetermined intervals,means between the display frame and the magazine for grasping the Said card and moving it into the display frame, said display frame having means for constraining the lower edge of the card to swing forward when it is released from the grasping means, means for engaging the lower edge of the card and holding it in displayed position, means for grasping the lower end of the card, and moving it downward when the holding means is released, said holding 10 means being operated by the lifting of the rearmost card, and means for guiding the displayed card into the magazine.
